如图1所示本发明的一个具体实施例，基座8由并排设置且一端连接的两块基座板81组成，所述升降移动部41通过导轨副安装在两块基座板81的连接端，并通过同样安装在基座8上的垂直驱动装置5驱动升降，所述的导轨副可采用已知的导轨副结构，它不仅限定升降移动部41只能作延垂直方向(即相对于基座8的上下方向)的直线移动，还能使升降移动部41承载较大的水平方向的二维力和空间的三维力矩，以确保在人体及设备重量的作用下，升降移动部41能平稳、安全地作升降移动。所述基座8的两块基座板81底部四个端角安装有四个万向轮9，所述的四个万向轮9分布情况如图5和图6所示，基座8底部的四个端角安装有四个万向轮9，所述垂直驱动装置5安装在一对后万向轮92一侧的基座8上，所述水平支撑臂42安装有平衡支架1的一侧对应的是两个前万向轮91，所述的垂直驱动装置5纵向中心轴A至所对应前万向轮91纵向中心轴B的距离D2大于垂直驱动装置5纵向中心轴A与平衡支架1在伸缩臂3未伸出状态下的中心线C之间形成的最大中心轴距离D1。万向轮作为基座与地面之间的受力点，合理的分布于基座边缘下位置，确保了移动式升降器在工作时平稳可靠地移动。所述的万向轮9也可以为至少三个。
所述的水平支撑臂42向基座8底部未连接的一侧沿水平方向延伸，水平支撑臂42端部安装有垂直于水平支撑臂42放置的固定横杆43，所述固定横杆43两端各固定有一通过支架锁扣2与固定横杆43相连接的平衡支架1，所述 的平衡支架1为对称结构其两端各设有一个用于钩住人体支撑件20两侧担架杆23的支架钩11，支架钩11分布排列在固定横杆43的两侧，从而可实现相对垂直于水平支撑臂42对人体支撑件20进行横向钩吊，横向钩吊的方式节省了钩吊过程所需要的空间，同时使钩吊过程中人体支撑件20的重心始终靠近升降移动部41一侧，使升降及移动的过程更为稳定。容易想到的是，固定横杆43上可横向排列有多个平衡支架1，其中固定横杆43的两端各设置有一个平衡支架1为优选设计，在保证装置稳定性的前提下达到节省材料的目的，此外，也可以是四个支架钩11呈矩阵排列在固定横杆43上的整体式固定横杆43结构，使吊钩结构更为简单。特别地，水平支撑臂42端部可加装由水平驱动装置10驱动的伸缩臂3，所述的水平驱动装置10安装在水平支撑臂42内并与伸缩臂3驱动连接，所述的伸缩臂一端与水平驱动装置10连接，另一端与固定在水平支撑臂42端部的固定横杆43连接，从而可通过驱动伸缩臂3带动安装在伸缩臂3一端的固定横杆43沿水平方向向外侧延伸。本发明的伸缩臂可轻松地对吊起的人体支架进行平移动作，使得移动式升降器的操作更为灵活。
上述实施例中基座8的基座板81为固定式的结构，是普遍常用的一种基座形式，适用于病房、敬老院以及家庭使用等普通看护场所。此外，基座8还有两种适用于特殊情况下的两个实施例。
其中一种实施例的结构如图12所示，基座8中部安装有向平衡支架1方向延伸的支撑臂83，所述的支撑臂83与基座8内的驱动装置84驱动连接，所述的驱动装置84可驱动支撑臂83的端部85向下倾斜至端部85与地面接触并形成支点。本实施例的支撑臂可通过驱动装置使支撑臂的高度降低，从而实现支撑臂可进入到底座比较低的检查设备底部间隙内，并完成后续的钩吊支撑件的工作。例如：个别核磁共振设备的底部间隙就比较低，只能通过支撑臂的延伸来降低基座的高度。
另一种实施例的结构如图13所示，基座8包括两块并排设置的基座板81，两块基座板81之间驱动连接有展开驱动装置87，并且每块基座板81与基座8的连接端设置有展开支点86，所述的每块基座板81由展开驱动装置87驱动分别绕展开支点86相对于基座水平中线P以角度α向两侧展开。本实施例的基座机构可以向两侧外扩，适用于类似于手术台这种工作底盘落地并且底盘宽于升降器宽度的情况使用。本发明的垂直驱动装置5可以为气动驱动装置，所述的气动驱动装置产生的气压推动升降移动部41向上顶起。所述的垂直驱动装置5除了可采用气动驱动装置，还可以采用其它类型的驱动装置，如螺杆齿轮式手动驱动装置、蜗轮蜗杆螺杆式电动驱动装置或者液压驱动装置，可优选蜗轮蜗杆螺杆式电动驱动装置、气动驱动装置、螺杆齿轮式手动驱动装置、液压驱动装置中的一种或其中两种的组合，即：垂直驱动装置5为蜗轮蜗杆螺杆式 电动驱动装置和/或螺杆齿轮式手动驱动装置；或者，垂直驱动装置5为液压驱动装置或蜗轮蜗杆螺杆式电动驱动装置。垂直驱动装置5都包括常规的固定部件和移动部件，将固定部件固定安装在基座8上，而所述的移动部件与升降移动部41驱动联接，即垂直驱动装置5安装在基座8上、并与升降移动部41驱动联接。这里所述的驱动联接是指能将动力传输给升降移动部41的联接，如气缸(图中未示出)的活塞顶杆直接将升降移动部41向上顶起的联接结构。应当能理解到，螺杆齿轮式手动驱动装置包括由螺杆(图中未示出)和螺母(图中未示出)组成的螺杆传动机构、由齿轮(图中未示出)组成的齿轮传动机构和手柄(图中未示出)，螺杆传动机构用于将转动转换为直线移动，而齿轮传动机构用于转换转动方向和传动比，动力通过手柄驱动齿轮转动，齿轮转动驱动螺杆传动机构推动升降移动部41直线移动。如果用电机(图中未示出)驱动齿轮转动，则成为蜗轮蜗杆螺杆式电动驱动装置，。类似于气动驱动装置，液压驱动装置包括液压缸(图中未示出)和液压泵(图中未示出)，液压泵产生的液压通过液压缸推动升降移动部41向上顶起。本发明的垂直驱动装置可手动驱动也可自动驱动，并且自动驱动方式的垂直驱动装置可有多种形式，使垂直驱动装置的驱动方式更加灵活，优选的是蜗轮螺杆式电动驱动装置，其优点是在承载时具有自锁的功能，并且噪音低，结构简单。
本发明驱动医用移动式升降器工作的电源可通过连接外部的电源提供，也可以通过安装在基座8内的蓄电池7提供，可在无电源或停电的环境下保证装置的正常工作，增加了装备使用的灵活性同时提高了设备工作可靠性。此外，所述的基座8上安装有可对充气床垫充气的气泵6。所述的充气床垫可以是例如专利号为CN201410068892.9所涉及的多功能床垫200，所述的气泵6通过床垫的充气嘴22和充气导管21对床垫进行自动充气，增强了医用移动式升降器的实用功能。
如图2-4所示本发明的平衡支架1的结构，所述的平衡支架1两侧为对称结构并通过支架锁扣2与固定横杆43固定连接，所述的支架锁扣2一端与固定横杆43固定连接，另一端通过导向销17与平衡支架1中部设置的支架锁槽13相连接，所述的支架锁槽13与支架锁扣2端部向外延伸出的斜面形状相匹配并且相互形成斜度配合限位。平衡支架与支架锁扣之间的连接结构简单，且支架锁扣与支架锁槽的斜度配合有利于实现支架锁扣与平衡支架的固定，避免平衡支架的晃动造成对患者的伤害，且能够平衡支架工作时的可靠承重力。
如图2所示本发明的平衡支架1的一个具体实施例，所述的平衡支架1为拱门型结构，所述拱门型结构的两侧端部延伸出一对相对设置的内弧形半封闭结构的支架钩11a和11b。所述半封闭结构的开口分别设置在支架钩11a弧形半封闭结构的第一象限和支架钩11b弧形半封闭结构的第二象限。支架钩通过 向内弧形半封闭结构的力学防滑扣设计，在弧形半封闭结构形成圆的第三、四象限内承受向下作用力时，可完全可靠避免作用力臂出现滑扣隐患。平衡支架1中部还设置有用于与支架锁扣2相固定连接的支架锁槽13，所述支架锁槽13的中心点0位置设置有与导向销17连接的支架孔14，所述中心点0下方以平衡支架中线a为对称轴两侧对称设置有一对凹孔15，所述的凹孔15可与支架锁扣2上的凸起弹性件16配合对平衡支架1的摆动过程进行限位固定。
如图3所示本发明的平衡支架1与支架锁扣2的连接结构，所述支架锁扣2沿两侧延伸出两片形状相同且相对设置的固定片201，每片固定片201上设置有两端为半圆弧形且两端圆心之间的距离为H的导向槽18，相对设置的固定片201夹持支架锁槽13并通过导向销17将支架锁槽13内的支架孔14和固定片201上的导向槽18相连接，从而配合形成平衡支架1与支架锁扣2之间的铰链连接，平衡支架通过与支架锁扣之间的铰链连接实现简单方便且稳定牢固的连接方式。同时，导向销17可沿导向槽18运动并带动平衡支架1上下运动使支架锁槽13与支架锁扣2之间产生可供平衡支架1沿支架锁扣2的垂直方向左右摆动的配合间隙，通过可上下调节的平衡支架，实现平衡支架左右摆动，可使挂钩人体支撑件的过程方便灵活；并且当平衡支架1向垂直驱动装置5一侧旋转角度R时，该升降器的体积更小有利于不工作时的移动和储放。此外，固定片201的端部向外延伸出的斜面形状与支架锁槽13的形状相匹配实现承力时支架锁扣与平衡支架的固定，支架锁扣2与支架锁槽13配合的端部的宽度大于支架锁扣2上设有导向槽18的活动部的宽度。特别地，优选支架锁扣2的端部形状为等腰梯形可使支架锁扣2的端部受力平衡，实现平衡支架钩吊及移动工作过程稳定。当然支架锁扣2的端部形状还可以是圆形、半圆形、椭圆形、半椭圆形、多边形等异形结构，支架锁槽13的形状与支架锁扣2的端部形状相匹配，如可以为与椭圆形、半椭圆形匹配的半椭圆形。优选的等腰梯形结构使得平衡支架1沿导向槽18上下运动后左右摆动时支架锁槽13的侧壁可与支架锁扣2中部的侧壁较好的配合。容易想到的是，支架锁扣2与平衡支架1不限于上述实施例的连接结构，支架锁扣2可沿端部延伸出与上述实施例相同的一片固定片201，并通过导向销17将支架锁槽13内的支架孔14和固定片201上的导向槽18相连接，同样可以达到上述实施例所能实现的功能，同时不采用铰链连接的方式使结构更为简单。
如图4所示本发明平衡支架摆动状态示意图，所述的导向销17带动平衡支架1沿导向槽18上下运动且移动的最大距离为H，当导向销17带动平衡支架1从导向槽18的最底部向上移动距离H的过程中，固定片201端部所延伸出的斜面将不再受到与其匹配的支架锁槽13的限位固定，从而产生可供平衡支架1沿支架锁扣2的垂直方向左右摆动的配合间隙，使平衡支架1可沿平衡支架中线 a以角度R左右摆动，可摆动的平衡支架1便于钩挂担架杆23的操作，同时完成对担架杆23的钩挂后由于重力作用导向销17会带动平衡支架1恢复至移动前位置，并且固定片201端部所延伸出的斜面将重新被支架锁槽13限位固定，使医用移动式升降器可稳定安全地继续完成后续的升降和移动工作。此外在摆动的过程中，所述支架锁槽13内的中心点0下方两侧对称设置的一对凹孔15与导向槽18中部两侧对应设置的凸起弹性件16可在摆动的过程中对平衡支架1的摆动幅度进行限位固定。通过设置平衡支架摆动的限位装置，在保证平衡支架灵活性的前提下提高工作效率。
容易想到的是凹孔15与凸起弹性件16的位置关系不仅局限于上述实施例的情况，如图9至图11所示平衡支架1的另一实施例。支架锁槽13的中心点0上方以平衡支架中线a为对称轴两侧对称设置有一对凹孔15，所述的一对凹孔15与导向槽18上方设置的凸起弹性件16可在摆动的过程中对平衡支架1的摆动幅度进行限位固定。
本发明的平衡支架1还可以是如图14至24所示的伸缩结构，具有伸缩结构的平衡支架1包括安装支架110和至少一个伸缩支架120，每个伸缩支架120分别安装在安装支架110内并与安装支架110滑动连接，伸缩支架120可沿安装支架110相对移动并缩进安装支架110内。伸缩支架120的端部还设有用于钩吊人体支撑件20的支架钩11，伸缩支架120可滑动伸出安装支架110从而使得平衡支架1将人体支撑件20吊起。
容易想到的是，平衡支架1具有展开与收缩两种使用状态，其中平衡支架1在钩吊人体支撑件20时处于如图14或图20所示的展开状态，此时伸缩支架120完全伸出安装支架110从而使得支架钩11可分别对应钩住人体支撑件20的两侧。另外平衡支架1在闲置时处于如图15或21所示的收缩状态，此时伸缩支架120收缩滑入安装支架110内从而使得平衡支架1在收缩状态时的整体空间小于展开状态时的整体空间。可伸缩的平衡支架结构简单节省了使用空间，提高了平衡支架的使用灵活性。
所述的平衡支架1安装在固定横杆43上可从人体支撑件20的两侧将其钩吊悬挂在固定横杆43的下方，图1中的固定横杆43上可并排安装有至少一个平衡支架1，并且固定横杆43与水平支撑臂42的端部相连接，所述的水平支撑臂42端部包括由水平驱动装置10驱动的伸缩臂3，可通过驱动伸缩臂3带动安装在伸缩臂3一端的固定横杆43沿水平方向移动，水平支撑臂42还与升降移动部41驱动连接，所述的升降移动部41安装在基座8上并与基座8上的垂直驱动装置5驱动连接，所述的基座8底部安装有万向轮。平衡支架应用于可升降平移的移动设备上，提高了平衡支架使用的灵活性保证了移动病人过程的安全可靠性，同时驱动装置提高了移动设备的自动化程度，使得操作移动过 程简便。
具体地，如图14至19所示的是具有伸缩结构的平衡支架1的第一种实施例，本实施例中的平衡支架1分别包括一个安装支架110和一个伸缩支架120，所述的伸缩支架120滑动安装在安装支架110的滑腔111内，并且安装支架110和伸缩支架120的端部分别设有支架钩11，所述的支架钩11可对应钩吊人体支撑件20的两侧。一个安装支架和一个伸缩支架使得平衡支架结构简单，提高了平衡支架组装效率及使用灵活性，同时保证了钩吊的稳定可靠。图14所示的是本实施例的平衡支架1在展开状态时的结构，此时伸缩支架120完全伸出安装支架110且二者端部设置的支架钩11相对于平衡支架1的中线A对称设置。图15所示的是本实施例的平衡支架1处于闲置的收缩状态时，伸缩支架120缩进安装支架110的滑腔111内从而达到节省空间便于放置的目的。
优选地，在平衡支架1处于用于钩吊人体支撑件20的展开状态下，安装支架110和伸缩支架120构成如图14所示的拱形结构的平衡支架1，支架钩11分别设置在拱形结构的平衡支架1的两侧端部，伸缩支架120可沿安装支架110作弧线运动。平衡支架完全展开后呈拱形结构便于操作，提高了平衡支架的使用效率，同时伸缩支架沿弧线收缩进安装支架进一步节省了平衡支架的所占空间，提高了平衡支架使用的便捷性。
如图19中所示的平衡支架1的侧面结构，平衡支架1的安装支架110由两片安装支架片110a和110b拼装而成，所述的两片固定片110a和110b内形成有用于伸缩支架120滑动的滑腔111，图17所示的安装支架110的滑腔111的内壁顶部设有可与图16所示的伸缩支架120的端部上边沿的限位块121对应匹配连接的限位卡槽112，滑腔111的内壁底部设有可与伸缩支架120的下边沿接触连接的受力块113，如图24所示的限位卡槽112和受力块113在伸缩支架120伸出安装支架110时分别用于限位和支撑伸缩支架120。由安装支架片拼装形成的滑腔结构简单保证了伸缩支架滑动的稳定性，同时限位卡槽及受力块有效地保证了平衡支架在钩吊人体支撑件过程中的平衡稳定性，提高了平衡支架的安全可靠性。
伸缩支架120与安装支架110相接触滑动的方式不仅限于上述一种情况，还可以是如图18所示的滑动方式，图18中的安装支架110内设有导向柱114，所述的伸缩支架120上开设有与导向柱114配合滑动连接的导向槽122，所述的导向柱114可在导向槽122内滑动从而使得伸缩支架120沿安装支架110相对移动，并且滑腔111的内壁底部同样设有可与伸缩支架120的下边沿接触连接的受力块113。导向柱与导向槽的滑动配合结构简单提高了使用效率，同时导向槽保证了伸缩支架滑动过程的准确性，提高了平衡支架收缩与展开过程的一致性。
如图18和图19所示的平衡支架1通过支架锁扣2安装在固定横杆43上，支架锁扣2一端与固定横杆43连接，另一端沿两侧延伸出两片形状相同且相对设置的固定片201，图18中的固定片201通过导向销17与安装支架110上的支架孔14配合形成平衡支架1与支架锁扣2之间的锁扣连接。平衡支架的安装支架通过锁扣结构实现了平衡支架与固定横杆的稳定连接，提高了钩吊过程的可靠性。特别地，图19中的支架锁扣2相对应设置的固定片201之间形成了用于导向销17带动平衡支架1上下移动的移动腔202，所述固定片201的侧面上安装有置于移动腔202内的限位开关203，所述的限位开关203分别与水平驱动装置10和垂直驱动装置5相连接，所述的支架孔14上还设有置于移动腔202内用于触发限位开关203的触发块141。可上下移动的平衡支架在钩吊操作的过程中更为灵活，同时限位开关使得平衡支架在移动超过规定幅度时对移动装置进行紧急停止操作，保证了移动过程的安全性。优选地，如图19所示的固定横杆43上并排安装有两个平衡支架1可将人体支撑件20水平吊起，并且固定横杆43可与水平支撑臂42的端部驱动连接。
如图20至23所示的是具有伸缩结构的平衡支架1的第二种实施例，所述安装支架110的两侧分别设有至少一个伸缩支架120，所述的伸缩支架120滑动安装在安装支架110的滑腔111内，并且每个伸缩支架120的端部分别设有支架钩11，所述的支架钩11可对应钩吊人体支撑件20的两侧。安装支架的两侧分别设有可伸缩的平衡支架保证钩吊人体支撑件时的平衡稳定性，提高了平衡支架使用过程的安全性，同时两侧的伸缩支架均可收缩至安装支架内，节省了平衡支架的使用空间。图20所示的是本实施例的平衡支架1在展开状态时的结构，此时安装支架110两侧的伸缩支架120完全伸出安装支架110且伸缩支架120端部设置的支架钩11相对于平衡支架1的中线对称设置。图21所示的是本实施例的平衡支架1处于闲置的收缩状态时，安装支架110两侧的伸缩支架120缩进安装支架110的滑腔111内从而达到节省空间便于放置的目的。
优选地，在平衡支架1处于用于钩吊人体支撑件20的展开状态下，安装支架110和伸缩支架120构成如图20所示的拱形结构的平衡支架1，支架钩11分别设置在拱形结构的平衡支架1的两侧端部，伸缩支架120可沿安装支架110作弧线运动。并且滑腔111及伸缩支架120上设有与第一种实施例结构相同的限位块121、限位卡槽112及受力块113，从而实现对安装支架110两侧伸缩支架120的限位支撑。容易想到的是，本实施例中伸缩支架120与安装支架110相接触滑动的方式也可以采用安装支架110内设有导向柱114及伸缩支架120上开设有与导向柱114配合滑动连接的导向槽122的安装方式。特别地，滑腔111的两侧还安装有与伸缩支架120对应设置并与水平驱动装置10和垂直驱动装置5相连接的第二限位开关115，第二限位开关的作用与限位开关203 的作用相同均是防止移动的过程中平衡支架的摆动幅度过大造成安全隐患。
如图22和23所示的平衡支架1固定安装在固定横杆43上，所述的固定横杆43与水平支撑臂42铰链连接可相对于水平支撑臂42上下移动，并且水平支撑臂42上设有与固定横杆43相对应的限位开关203，所述的限位开关203分别与水平驱动装置10和垂直驱动装置5相连接。平衡支架直接与固定横杆相连接且固定横杆与水平支撑臂铰链连接的方式使得装置连接结构简单，提高了使用效率。图22中的安装支架110的两侧分别设有两个伸缩支架120可将人体支撑件20水平吊起，并且固定横杆43与水平支撑臂42铰链连接。
如图5和图6所示的是移动式升降器将患者升起一定距离D的状态时的两种操作模式。升降臂4在垂直驱动装置5向上作用力的情况下，通过支架锁扣2的斜度与支架锁槽13的斜度配合以及支架孔14、导向销17、导向槽18的配合于平衡支架工作时的进一步可靠承力，给一对支架钩11a和11b产生作用力将担架杆、多功能床垫和患者或者将担架杆、支撑件与患者通过以下两种操作模式向上升起；具体实施方式如下：
第一种模式是当患者需要移动至其它推车、治疗、检查仪器上等诊疗服务时。首先在移动式升降器万向轮9、水平驱动装置10和垂直驱动装置5的协同作用下，可使平衡支架1调整至与担架杆23操作空间基本相对应的位置，此时平衡支架1在手动作用下使一对支架钩11a和11b钩住穿入多功能床垫200的担架杆23，接着操作移动式升降器控制面板(图中未画出)，在垂直驱动装置5向上的作用力下，致支架锁扣2向上运动，平衡支架1在支架锁槽13和支架锁扣2相互运动下自动锁住，将担架杆23、多功能床垫200、患者一并升起需要的高度D。此时，通过万向轮9和伸缩臂3的协同作用，可移动托起患者至其他推车或需要的相应位置；操作控制面板，在垂直驱动装置5向下的作用力下，将多功能床垫200、担架杆23、患者一并放置至推车或治疗、检查仪器上，在手动作用下将一对支架钩11a和11b与担架杆分离，取出担架杆。实现轻松、平稳地将患者升起、移动至其它治疗、检查仪器上的功能。
第二种模式在日常的病房护理时，需要对患者更换床单及其它护理工作等服务时。首先在移动式升降器万向轮9、水平驱动装置10和垂直驱动装置5的协同作用下，可使平衡支架1调整至与担架杆操作空间基本相对应的位置；此时平衡支架1在手动作用下使一对支架钩11a和11b钩住已扣上支撑件的担架杆，操作移动式升降器控制面板(图中未画出)，在垂直驱动装置5向上的作用力下，致支架锁扣2向上运动，平衡支架1在支架锁槽13和支架锁扣2相互运动下自动锁住，将担架杆、支撑件、患者一并升起一定的高度D(如图6)。就此状态，护工可对患者更换床单及相关的护理工作，整理就绪后操作控制面板，在垂直驱动装置5向下的作用力下，将担架杆、支撑件、患者一并平稳放 置至整理完毕的整洁床位上，在手动作用下将一对支架钩11a和11b与担架杆分离，取出支撑件、担架杆。实现给患者平稳、轻松地更换床单和护理的功能。
如图7所示，本发明另一种实施例的结构示意图，本发明的医用移动式升降器，包括相互连接的升降移动部41和水平支撑臂42，所述的升降移动部41底部安装在基座8内并与基座8内的垂直驱动装置5驱动连接，基座8内安装有蓄电池7且底部安装有万向轮9。所述的平衡支架1沿水平支撑臂42向外延伸的方向排列安装在水平支撑臂42上，可平行于水平支撑臂42对人体支撑件20进行钩吊，由于人体支撑件20是平行于水平支撑臂42的纵向钩吊方式，相比于上一个实施例所提到的横向钩吊方式，会产生在钩吊人体支撑件20的过程中重心距离升降移动部41过远导致医用移动式升降器发生倾斜甚至偏倒的情况，为避免此种危险的情况发生，本实施例的基座8在水平支撑臂42所延伸方向的另一侧安装有配重块82，放置重心偏离导致的倾斜和偏倒情况。
本发明的人体支撑件20可为担架或者两侧带有担架杆23的床垫或由若干个支撑件和担架杆组合的担架，可适用于多种人体支撑件灵活使用，通用性强。所述的床垫可为多功能床垫200，如图8所示，所述的多功能床垫包括床垫本体和分立的两个担架杆23，床垫本体上设有多个气囊25、与气囊25贯通的是充气导管21，基座8上设置的气泵6通过充气导管21端部设置的充气嘴22可对气囊25进行充气。所述的担架杆23可插入到床垫本体两侧的担架孔24内，再通过医用移动式升降器上的平衡支架1两端设置的支架钩11钩住多功能床垫200两侧安装的担架杆23，从而实现对多功能床垫200稳定地升降和移动。
以上所述仅为本发明的推荐实施例和相关操作过程说明，而不是对本发明专利的限制，尤其是移动式升降器本体不限于和上述附件的人体支撑件、气泵、担架杆等的配合使用，因此可以联想到能够对患者在医疗期间涉及更优质管理和人性化服务方面的升降器上功能的修改和变化均落入本发明专利的保护范围之内，所有修改和变化都在发明构思的范围内，所有细节都可以用技术上相同或等同元件代替，皆应视为本发明的涵盖范围之内。
